[0002] In modern industrial production, H-shaped steel is popular due to its high strength and excellent stability, and is widely used in many fields such as construction, machinery manufacturing and equipment installation. In order to meet the needs of different fields, H-shaped steel often needs to be precisely cut. However, the fixation work before cutting is crucial.

[0003] At present, the traditional way to fix H-beams is usually for workers to use handle bolts to fix H-beams, that is, by rotating the handle bolts on both sides of the H-beam to clamp and fix the bottom walls on both sides. However, this method has obvious shortcomings in operation: after the H-beam is cut, the workers need to manually loosen multiple handle bolts one by one to release the limit of the H-beam after cutting, which not only increases the workload of workers, but also seriously affects work efficiency. More importantly, long-term manual operation can easily make workers tired, which may cause the bolts to fail to be fully tightened, and then the H-beam will become loose during the cutting process, which will undoubtedly damage the processing quality of the H-beam.

DETAILED DESCRIPTION

[0022] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limitations on the present invention. On the contrary, the embodiments of the present invention include all changes, modifications, and equivalents that fall within the spirit and connotation of the appended claims.

[0023] The H-beam fixing tool of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 6 As shown, the H-beam fixing tool of the embodiment of the utility model may include a U-shaped frame 10, two guide rods 20, two support plates 30, two support devices 40, a transmission mechanism 50 and a retractable device 60.

[0025] The two guide rods 20 are arranged side by side and horizontally in the U-shaped frame 10 , and the two support plates 30 are symmetrically arranged in the U-shaped frame 10 and located on both sides of the two guide rods 20 .

[0026] The two supporting devices 40 are symmetrically arranged in the U-shaped frame 10 , and the two supporting devices 40 are slidably connected to the two guide rods 20 and the corresponding supporting plates 30 , respectively.

[0027] The transmission mechanism 50 is rotatably disposed between the two support plates 30 , and the transmission mechanism 50 is connected to the two support devices 40 respectively.

[0028] The retractable device 60 is disposed on the U-shaped frame 10 , and an output end of the retractable device 60 is connected to one of the supporting devices 40 .

[0029] It should be noted that the retractable device 60 described in this embodiment may be a cylinder, a hydraulic cylinder or an electric retractable rod, and the initial state of the output end of the retractable device 60 is an extended state.

[0030] In order to clearly illustrate the above embodiment, in one embodiment of the present utility model, as Figure 1-Figure 5 As shown, the supporting device 40 may include an L-shaped supporting frame 41 , a plurality of supporting rollers 42 , a support roller 43 , two racks 44 and two sliders 45 .

[0031] The L-shaped support frame 41 is slidably mounted on the two guide rods 20 , and one of the L-shaped support frames 41 of the two support devices 40 is connected to the output end of the retractable device 60 .

[0032] A plurality of support rollers 42 are arranged side by side and rotatably disposed at the bottom end of the L-shaped support frame 41. For example, the plurality of support rollers 42 may be 2, 3, 4, or 5 support rollers 42, etc. The specific number of support rollers 42 may be selected according to actual conditions and is not limited here. The plurality of support rollers 42 are respectively connected to the bottom wall of the U-shaped frame 10. It should be noted that the support rollers 42 described in this embodiment play a role in supporting the L-shaped support frame 41 and can reduce the resistance of the L-shaped support frame 41 moving on the U-shaped frame 10.

[0033] The roller 43 is rotatably arranged at the top of the L-shaped support frame 41 , and two racks 44 are symmetrically arranged on the two side walls of the L-shaped support frame 41 , wherein two slide grooves 301 are respectively provided on the opposite surfaces of the two support plates 30 .

[0034] It can be understood that by arranging the rollers 43 on the L-shaped support frames 41, when the H-shaped steel placed on the top of the two L-shaped support frames 41 needs to be tightened and fixed, as the two L-shaped support frames 41 move away from each other, the rollers and the H-shaped steel rotate and contact, thereby effectively avoiding friction damage to the H-shaped steel, and further effectively ensuring the processing quality of the H-shaped steel.

[0035] The two sliders 45 are slidably disposed in the corresponding sliding grooves 301 on the two support plates 30 , and the two sliders 45 are fixedly connected to the corresponding side walls of the rack 44 .

[0036] Further, in one embodiment of the present invention, Figure 4 and Figure 5 As shown, the transmission mechanism 50 may include a support shaft 51 and two gears 52 , wherein the support shaft 51 is rotatably disposed between the two support plates 30 .

[0037] The two gears 52 are arranged side by side and sleeved and fixed on the support shaft 51 , and the two gears 52 are respectively meshed with the corresponding racks 44 in the two support devices 40 .

[0038] It should be noted that each gear 52 described in this embodiment is meshed with the corresponding racks 44 in the two supporting devices 40 respectively, that is, one gear 52 is meshed with two racks 44 symmetrically distributed up and down at the same time.

[0039] Specifically, in order to meet the needs of different fields (for example, construction and machinery manufacturing fields, etc.), when it is necessary to cut the H-beam, the staff can first fix at least two H-beam fixing fixtures side by side on the frame of the workbench (the workbench can be the workbench of the cutting machine), and then the staff can control the hoisting machine to hoist the H-beam to be cut between the two H-beam fixing fixtures, and support the H-beam through the two supporting devices 40 in each H-beam fixing fixture, refer to the attached Figure 6 As shown, the H-shaped steel is now located on the rollers 43 in the two supporting devices 40 .

[0040] Then, the staff controls the output end of the retractable device 60 to retract, and pulls one of the L-shaped support frames 41 to move along the guide rod 20. The moving L-shaped support frame 41 drives the gear 52 to rotate through two of the racks 44 (i.e., the racks arranged on the two side walls of one of the L-shaped support frames 41). The rotating gear 52 pushes the other L-shaped support frame 41 to move backward along the guide rod 20 through the other two racks (i.e., the racks arranged on the two side walls of the other L-shaped support frame 41). The two L-shaped support frames 41 moving backwards hold the H-shaped steel tightly and securely.

[0041] When the H-shaped steel needs to be loosened after cutting, the worker can control the output end of the retractable device 60 to extend, thereby driving the two L-shaped support frames 41 to move toward each other, thereby loosening the H-shaped steel that is tightly fixed. In this way, the H-shaped steel can be stabilized efficiently without excessive manual operations, which not only reduces the burden on workers, but also improves the overall efficiency of fixing and releasing the H-shaped steel.

[0042] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, a plurality of equidistant and parallel grooves 401 are provided on the top side wall of the L-shaped support frame 41. For example, the plurality of grooves 401 may be 3, 4, 5, 6, 7, 8 grooves 401, etc. The specific number of grooves 401 may be selected according to actual conditions and is not limited here.

[0043] It is understandable that by opening a groove 401 on the top side wall of the L-shaped support frame 41, a plurality of convex strips can be formed on the side wall of the L-shaped support frame 41. The plurality of convex strips can be pressed into contact with the top wall of the H-shaped steel, thereby reducing damage caused during the tightening process of the H-shaped steel.

[0044] In one embodiment of the present invention, Figure 2 and Figure 4 As shown, two groups of symmetrically distributed mounting seats 70 are provided on the bottom wall of the U-shaped frame 10, and each group of mounting seats 70 may include two symmetrically distributed mounting seats 70. That is, four mounting seats are symmetrically distributed in pairs on the U-shaped frame 10. It should be noted that the mounting seats 70 described in this embodiment are provided with mounting holes.

[0045] It can be understood that by providing the mounting seat 70 , it is convenient to fix the U-shaped frame 10 on the workbench frame.

[0046] In summary, the H-beam fixing tool of the embodiment of the utility model can effectively stabilize the H-beam without excessive manual operation, which not only reduces the burden on workers but also improves the overall efficiency of fixing and releasing the H-beam.
